* introducing dct248 into the DSP context.
* simple/accurate implementation of dct248
* DV encoding now supports 2-4-8 DCT
* DV encoding gets a bit faster (but still miles away
from what I think it could do)
* misc. DV codec cleanups
Originally committed as revision 2425 to svn://svn.ffmpeg.org/ffmpeg/trunk
